Speaking earlier this week in support of the ban, Home Secretary Charles Clarke said: "Recent events in London and elsewhere in the world have shown all too clearly that the threat posed by global terrorism has not gone away.

"The attacks of 7 and 21 July have served as a stark reminder of the need to maintain a vigorous approach to dealing with terrorisms and their supporters.

"Proscription is an important power, and one not to be used lightly.

"The list of proscribed organisations is kept under constant review and, after careful consideration of all the relevant factors, I am satisfied that these groups should be added to it."

Mr Clarke said he was determined to act against groups that may not be involved in committing acts of terrorism, but still "provide succour or support for terrorist groups and their acts".

The Terrorism Bill, which is due to be published shortly, would amend the Terrorism Act 2000 to allow the proscription of organisations which glorify terrorism.

It would also cover proscribed organisations which change their names in an attempt to evade the law by continuing the ban to the renamed group.

The Liberal Democrats claimed there was not enough time given to debate the bans, but Commons leader pointed to what he called a proper opportunity during Thursday's sitting.
